4. The test time to measure 0.1 Hz to 10 Hz noise should not ex-
ceed 10 seconds. As shown in the noise-tester frequency-response
curve of Figure 8, the 0.1 Hz corner is defined by only one pole.
The test time of 10 seconds acts as an additional pole to elimi-
nate noise contribution from the frequency band below 0.1 Hz.
5. A noise-voltage-density test is recommended when measuring
noise on a large number of units. A 10 Hz noise voltage-density
measurement will correlate well with a 0.1 Hz to 10 Hz
peak-to-peak noise reading, since both results are determined
by the white noise and the location of the 1/f corner frequency.
6. Power should be supplied to the test circuit by well bypassed
low noise supplies, e.g. batteries. These will minimize output
noise introduced via the amplifier supply pins.

NOISE MEASUREMENT—NOISE VOLTAGE DENSITY
The circuit of Figure 9 shows a quick and reliable method of
measuring the noise voltage density of quad op amps. Each
individual amplifier is series-connected and is in unity-gain, save
the final amplifier which is in a noninverting gain of 101. Since
the ac noise voltages of each amplifier are uncorrelated, they
add in rms fashion to yield:
